This release is available in Chinese. New research indicates that a finding on a routine electrocardiogram that signals a disorder of the electrical conducting system in one part of the heart and ...

Sudden cardiac death resulting from fibrillation -- erratic heartbeat due to electrical instability -- is one of the leading causes of death in the United States. Now, researchers have discovered a ...

During a severe heart attack many heart muscle cells die and are replaced by scar tissue to stabilize the heart wall. Connective tissue cells, known as fibroblasts (FB), are the dominant cell type in ...

Heart rhythm problems occur when heart muscle cells fail to properly transmit electrical signals that coordinate blood pumping. Now, scientists at Duke University have devised a promising method to ...

Figure 2: Reduction in heart rate during atrial fibrillation after Gα i2 gene transfer. This study is the first report of intracoronary site-specific gene transfer and the first use of gene therapy to ...

Sept. 25 (UPI) --Researchers have succeeded in creating a digital twin that for the first time replicates the heart's electrical conduction system, which coordinates heartbeats, a new study says. The ...

Macrophages have a previously unrecognized role in helping the mammalian heart beat in rhythm. Researchers have discovered that macrophages aggregate around central cardiac cells that regulate ...

CINCINNATI, Ohio – We’ve all heard warnings about BPA, a chemical found in plastics and personal care products. Studies show that nearly 90% of Americans have detectable levels of BPA in their bodies.

The heart is a natural pump made of muscle tissue, and, like every muscle, it needs energy to function. The heart’s pumping action is regulated by an electrical conduction system that coordinates the ...

Cardiac physiologic pacing, also known as cardiac resynchronization therapy, is indicated in patients with heart failure, reduced left ventricular ejection fraction (LVEF) of 50% or less, and either a ...

Electrocardiologists are cardiologists who have received additional training in testing for and treating heart rhythm problems. Electrocardiologists are also known as electrophysiologists, cardiac ...
